PORTABLE SAW lVlILL.

$PECIFECATION' forming part of Letters Patent No. 309,056, dated December 9, 1884:.

Application filed August 29, 1884.

$0 all whom it may concern.-

Be it known that I, A. J. HUBER, a citizen of the United States, and a resident of Columbus Grove, in the county of Putnam and State of Ohio, have invented certain new and useful Improvements in Portable Saw-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure l is a plan view of my improved portable saw -mill, the wheels of the truck having been removed. Fig. 2 is a side view of the machine. Fig. 3 is an end view, and Fig. 4 is a detail view showing the mechanism for reversing the revolutions of the carriage-operating shaft.

The same letters refer to the same parts in all the figures.

This invention relates to portable saw-mills for sawing logs, fire-wood, and the like; and it has for its object to produce a machine which shall be simple in Construction, durable, and which may be easily and convenientlv transported from place to place and set up for operation without loss of time.

\Vith these ends in view the invention con-' sists in the in'lproved construction and con1- bination of parts which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A designates a rectangular frame or truck, mounted upon wheels l3 B, in order that it may be conveniently moved or transported from place to place. The rear end of thc'frame or truck A supports an upright boiler, (1, serving to geucrate the steanrsupply for a vertical engine, D, of suitable construction, mounted in front of the said boiler, and supplying the motive power for the saw-mill, as will be 1 1-escntly described.

E is a frame mounted or supported upon the truck A, and consisting, mainly, of a pair of forwardly-divcrging beams, F F, the rear ends of which are suitably bolted to the boiler, which is thereby braced in its proper position. The said frame has a cross-piece, G,

supporting the engine, and additional cross (No model.)

pieces H H and brackets I, which afford bearings for the several shafts of the machine.

J designates the main shaft, which receives its motion direct from the engine, and which is provided near its rear end with the balancewheel K. The main shaft is provided in front of the balance-wheel with a cone pulley, L, and in front of the latter with a friction-wheel, M, which is to be made of iron. The front end of the main shaft J carries the sawcollars N N and the clamping-nut O, by means of which the saw is mounted securely upon the said shaft or arbor.

l is a shaft arranged parallel to the main shaft J, and having a cone-pu1ley, Q, connected by a suitable belt or band with the cone pulley L upon the main shaft. The said shaft P also carries a friction-pulley, R,which is in contact with and receives motion from an intermediate friction-pulley, S, arranged between the'pulley R and the friction-wheel M.

T is a shaft arranged underneath the shaft 1 and having at its front end the feed-pinion U, which engages the rack of the log-carriage (not shown in the drawings,) which moves in the usual manner upon the tracks V V. The rear end of the shaft T is arranged in a bearing, \V, which has a slightly sliding motion, and which, my means of an eccentric, X, operated by a suitable hand lever, Y, maybe moved so as to cause a frictiorrwheel, Z, upon the rear end of the shaft T to engage either one of the friction pulleys R or M, thereby causing the shaft T and the carriage operated thereby to be moved in either direction.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood.

The construction of my improved portable saw-mill is exceedingly simple, as well as light and durable, thus enabling it tote constructed at a moderate expense, and rendering it particularly serviceable for the purposes intended.

I am aware that it is not broadly new to have a friction pulley upon the shaft which operates the gig or feeding mechanism in a saw-mill, which frictioirpulley may be brought to engage friction pulleys connected to and revolved from the saw-arbor, and revolving CID IOO
